Space-based X-ray observatory has ‘changed the way we do astronomy,’ says NASA Astrophysics Division director.

On July 23, 1999, NASA engineers deployed the Chandra X-Ray Observatory from the Columbia shuttle. A decade and a half later, the American space agency has decided to celebrate the 15th anniversary of the deployment by releasing four previously unpublished photos of supernova remnants.
